4 KMC Controls Network Cable Preparation Connecting a NetSensor to a KMC controller requires a six-wire cable with RJ-12 connectors on each end. Use either the KMC Controls ready-to-use cables or make cables to length when the NetSensor is installed. Cables made to length must meet the following requirements: Cable length is no longer than 75 feet (22.9 meters). Use cable with #24 AWG size conductors. Cable insulation must meet local building codes. Plenum rated cable is recommended. Connectors are appropriate for the cable in use and are installed following the connector manufactures instructions. RJ-12 CLOCK +5VDC A B GND DATA Cable Details 4

5 Rough-in preparation Complete rough-in wiring at each sensor location prior to sensor installation. This includes the following. Route the network cable from the NetSensor location to the controller to which it will connect. If required, install the appropriate mounting backplate. See Accessories on page 2 for model numbers. Mounting base RJ-12 cable Allen screws NetSensor mounting backplate Caution To prevent mounting screw heads from touching the circuit board in the NetSensor, use only the mounting screws supplied by KMC Controls. Using screws other than the type supplied will damage the NetSensor. Installing the NetSensor 1. Turn the Allen screws in the base of the NetSensor clockwise until they clear the cover. Swing the sensor away from the backplate to remove it. Turn clockwise to remove from base. Allen screws 2. Route the RJ-12 cable through the mounting base. 5

6 KMC Controls 3. Fasten the mounting base to the backplate or the outlet box with the Allen screws toward the floor. 4. Insert the RJ-12 cable coming from the base into the NetSensor. 5. Place the top of the NetSensor over the top of the mounting base and swing it down over the Allen screw brackets. Be careful not to pinch any wiring. 6. Back the Allen screws out of the brackets until they engage the NetSensor cover and hold it in place. Operation The following sections describe the controls and indicators found on the NetSensor. Setpoint buttons Fan speed Mode NetSensor button functions Display The display includes two 7-segment LCD digits that are visible across a normal size office. Room temperature is displayed until either setpoint button is pressed and then the display changes to setpoint mode. If the temperature remains out of the temperature operating range for more than 45 seconds, the KMD 1162 displays a set of dashes ( ). The NetSensor also sends 0 to the controller if the temperature is below 47 degrees Fahrenheit (8 degrees Celsius) and 120 if the temperature is above 97 degrees Fahrenheit (36 degrees Celsius). 6

7 Changing the setpoint Pressing either the up or down setpoint buttons changes the display from room temperature mode to setpoint mode. Pressing either button once displays the current setpoint for three seconds; each additional press increments or decrements the setpoint temperature by one degree Fahrenheit. Backlight When either setpoint button is pressed the backlight turns on and remains on for 10 seconds after the last button is released. PC port The NetSensor is equipped with a PC Port located at the bottom of the NetSensor housing. This port provides a temporary EIA 485 connection to the digital network for network setup. PC port Netsensor PC Port Location To use this port: 1. Connect the keyed, flat end of the KMD 5624 NetSensor Interface cable to the port on the NetSensor. 2. Connect the RJ-12 end of the cable to the interface device that converts the EIA 485 signal from the NetSensor into an EIA 232 signal. 3. The cable and interface required will vary between WinControl and BACstage. Cable and interface details are included in the installation guides for both programs. Maintenance Remove dust as necessary from holes in top and bottom. Clean the display with soft, damp cloth and mild soap. 7

8 KMC Controls Programming a NetSensor Program the KMD 1162 by associating each NetSensor button with a variable or value object in the controller to which the NetSensor is connected. See the illustration KMD 1162 button and function numbers on page 8 for the KMD 1162 button numbers. Table 3-1 lists the settings for programming a NetSensor with WinControl. Use the NetSensor dialog found under the Control Menu to configure each button. Table 3-2 lists settings for programming a NetSensor with BACstage. Use the NetSensor dialog in the Device Menu to configure each button. For additional instructions on programming a NetSensor with either WinControlXL or BACstage, use the on-line help system KMD 1162 button and function numbers 8

10 KMC Controls Temperature The space temperature sensor inside of the NetSensor displays room temperature. Configure the temperature sensor with an analog variable in WinControl or an analog value object in BACstage. Temperature is always programmed in the Button 1 position. Setpoint Button 2 is associated with an analog variable in WinControl or an analog value object in BACstage. The WinControl Range or BACstage Display Format must be set to 0. The NetSensor limits the setpoint values to a range between 47 and 97 degrees Fahrenheit (8 to 36 degrees Celsius.) Operators can view and change the setpoint by first touching Button 2 and then pressing an up or down arrow button. Write a Control Basic to control equipment based on the conditions of the setpoint. 10 IF VAR2 < VAR1 THEN START OUT6 Cool/Heat Button 3 is associated with a digital variable in WinControl or a binary value object in BACstage. When Button 3 is set to Off, the button value remains at the last Button 3 setting. Fan speed Button 4 is associated with an analog variable in WinControl or an analog value object in BACstage. The WinControl Range or BACstage Display Format must be set to 0. When Button 3 is set to Off, the value for Button 4 is set to 0. For the Button 4 positions LOW, MED, and HIGH, the button value is 1, 2, and 3 respectively. Verifying a functioning NetSensor To check if a functioning NetSensor is present, use the Control Basic function NETSENSOR-STATUS. 10 IF NOT NETSENSOR-STATUS THEN STOP OUT1 10
